What were you wearing this week? If it’s anything like what the five women chosen this week had on, you might have made some smart style choices–or some big a** fails. Let’s take a look at the most interesting ensembles of the week and figure out who looked fab and who failed. Shall we?

Rihanna

Rihanna arived at her Halloween party this week at Greystone Manor in West Hollywood looking very dark but very diva on the red carpet. Of course, this wasn’t her costume, but she wore this black on black ensemble to accept an award for being “Queen of West Hollywood.” Random I know. Anyway, for the occasion, she showed up in a black ribbed tank, a black skirt with lace panels and sheer booties to top it all off. Back to her half-shaven hairstyle, the singer made sure to give her look some extra pop (before she put the crown on) with a hot red lip. While some strappy heels or even a pair of heels with some color really would have taken this look to the next level, I don’t dislike it. It’s simple but still snazzy and I absolutely dig the skirt. I probably would have put this look together differently, but it’s not too bad. Steal.
